This is a very good copy of the classic Mott The Hoople bootleg, known on a double (original version vinyl) album as 'Rest In Peace' and on CD as 'Flash And Crash'.

The 'boot' notes suggest the concert recording was performed on the 13th April, however the poster from the gig, gives the concerts (matinee and evening or was it evening and very late evening?) as Friday 12th April 1974, perhaps they performed over two days at this venue.
